Understanding PCOS Hair Growth and Treatment Options

PCOS Hair Growth: What It Is (and Why It Happens)

When people search for ‘PCOS hair growth’, they are usually referring to hirsutism, which is the growth of dark, coarse hair in areas where women typically have less visible hair, including the face, chest, back, abdomen, and upper thighs.

In PCOS, higher androgen levels or increased sensitivity of hair follicles to androgens can cause fine, light hairs to become thicker and darker.^[1]

Over time, this can make hair more noticeable in androgen-sensitive areas of the body.

Unwanted hair growth is not simply a cosmetic concern. New or worsening hirsutism may be associated with PCOS or another hormonal condition, so getting an appropriate evaluation can help identify the underlying cause.

How Common Is Hirsutism in PCOS?

Hirsutism is one of the most common symptoms of PCOS, affecting an estimated 65% to 75% of women with the condition. Excess hair may develop in areas such as the face, chest, abdomen, or thighs.^[2]

For many people, unwanted hair growth can also affect confidence, body image, and everyday routines.

When Should You Get Evaluated?

A healthcare provider may ask about how quickly the hair developed, menstrual irregularities, acne or oily skin, scalp hair thinning, weight changes, family history, medications, and other symptoms.

Blood tests or additional evaluation may sometimes be recommended to rule out other causes of increased androgen activity.

Seek prompt medical evaluation if unwanted hair develops rapidly or appears alongside symptoms such as voice deepening, rapid increases in muscle mass, severe new acne, or other signs of significant androgen excess.

Treatment Goals

Treatment usually focuses on:

Slowing new hair growth
Making new hairs finer or less noticeable
Managing existing unwanted hair
Improving related symptoms such as acne
Treating other PCOS symptoms or metabolic concerns when necessary

Because medications primarily affect future hair growth, many people combine medical treatment with hair removal methods for existing hair.

Treatment Options for PCOS Hair Growth

The best approach depends on your symptoms, medical history, pregnancy plans, and treatment goals. Several options may be used alone or in combination.

Combined Hormonal Birth Control

Combined hormonal contraceptives are commonly used as a first-line treatment for hirsutism in people with PCOS who are not trying to become pregnant.^[3]

They can help reduce androgen activity and may improve both unwanted hair growth and acne over time.

Spironolactone

Spironolactone is an anti-androgen medication that blocks some of the effects of androgens on hair follicles. It may be considered when hirsutism remains bothersome after at least six months of hormonal and/or cosmetic treatment.

Because anti-androgens can affect a developing fetus, effective contraception is important when pregnancy is possible.^[4]

Topical Eflornithine

Topical eflornithine may be used to slow unwanted facial hair growth.

It does not remove existing hair, but it can reduce how quickly new facial hair grows and may be used alongside other hair removal methods.

Metformin

Metformin is primarily used in PCOS to address metabolic concerns such as insulin resistance and glucose regulation.

Although it can provide important metabolic benefits, it is not considered a primary treatment specifically for hirsutism. When the main treatment goal is reducing unwanted hair growth, hormonal treatments are generally more effective.

Metformin may still be appropriate for some people as part of their broader PCOS management plan.^[5]

Hair Removal Options

Hair removal methods can help manage hair that has already developed while medical treatments work to reduce future growth.

Short-term options include:

Shaving
Waxing
Threading
Plucking
Depilatory creams

For longer-term hair reduction, laser hair removal may be an option, particularly for darker hair.

Electrolysis is another method that can provide longer-lasting hair removal and may also be useful for lighter hairs that respond less effectively to laser treatment.

The most suitable method depends on factors such as hair color, skin tone, treatment area, cost, and personal preference.

How Long Does Treatment Take?

Hair follicles grow in cycles, so treatment does not produce immediate changes.

Medical treatments for hirsutism often need to be used consistently for several months before noticeable improvement occurs. In many cases, around six months of treatment may be needed before its effectiveness can be properly assessed.^[6]

Existing coarse hairs may still need to be removed cosmetically while treatment works to slow or reduce future growth.

Taking photographs periodically or keeping a symptom journal can make gradual changes easier to track.

Lifestyle Changes That May Help

Healthy lifestyle habits are an important part of overall PCOS management.

Depending on individual needs, this may include:

Regular physical activity
A balanced eating pattern
Adequate sleep
Stress management
Weight management when appropriate

These habits can support metabolic and reproductive health and may help improve some PCOS-related symptoms.

However, lifestyle changes should not be viewed as a guaranteed way to eliminate unwanted hair growth. They are best considered part of a broader PCOS management plan alongside treatments targeted specifically at hirsutism.

Questions to Ask Your Healthcare Provider

You may want to ask:

Does my hair growth suggest PCOS or another hormonal condition?
Do I need blood tests or other testing?
Which treatment is best suited to my symptoms and goals?
How long should I try treatment before assessing the results?
Would hormonal contraception or an anti-androgen be appropriate for me?
Could metformin benefit other aspects of my PCOS?
Which hair removal method is most suitable for my hair and skin type?
How should we monitor my progress?

Conclusion

PCOS-related hirsutism is common, and several treatment options are available.

Medical treatments can help slow future hair growth, while shaving, waxing, laser treatment, electrolysis, and other hair removal methods can manage existing hair. Lifestyle measures can also support broader PCOS management.

Because unwanted hair growth can have different causes and improvement takes time, getting an accurate diagnosis and developing an individualized treatment plan with a healthcare provider are important first steps.
